First, a later DLTOVR might fail if this is removed. Ensure that no DLTOVRs reference this OVRDBF.

Second, if parameter defaults have been modified or if a duplicate of the *CMD object exists with different parameters, then there might be overriden values that affect program execution. Make sure that neither of those conditions exist.

Third, programming later in the job might look for an override for ZFT00981 and cause different logic paths depending on existence or non-existence.

There might be other possibilities. Those are what come to mind immediately. None of them seem very likely, especially if there are no comments that indicate something unusual is being done.
